GPUGRID has like 70MByte tasks that take forever to upload and einstein has 4MByte tasks... those are about the largest I am aware of. If you are asking what completes fastest and therefore needs a lot of net uploads/downloads, eOn takes a couple minutes to finish and you can crunch a ton of them over the day...

climateprediction will send back like 3-4 30mb files back during the process of 1 work unit. the size could be more, take that with a grain of salt. i know that the computing for clean energy project for wcg sometimes has 20mb+ file sizes to upload.

Yes. that is the side of the 800D... it wouldn't cool enough without major mods... It needed 2 large radiators. Well, I figure two RX sized radiators would do it but needed a new box... I looked at Mountain Mods, XSPC, Danger Den, and others and decided the DD box was biggest bang for the buck.

Now, the 800D is being cleaned up and the 1090T Mobo/CPU and GTX 460's going into it...
